@bigkrys 请提供个代码片段试试

` draw(animationData,assetsPath,animationSpeed,loop,autoplay){
wx.createSelectorQuery().select('#c1').node(res => {
const canvas = res.node
context = canvas.getContext('2d')
let rate = 750/1334
canvas.width = (_that.data.width) * _that.data.pixelRatio
canvas.height = (_that.data.width * rate ) * _that.data.pixelRatio
canvas.top = 0
canvas.left = 0
context.scale(_that.data.pixelRatio, _that.data.pixelRatio)
lottie.setup(canvas)//要执行动画，必须调用setup,传入canvas对象
_that.changeAnimationType(animationData,assetsPath,animationSpeed,loop,autoplay)
}).exec()
},
changeAnimationType(animationData,assetsPath,animationSpeed,loop,autoplay){
animation = lottie.loadAnimation({
loop: loop,//是否循环播放（选填）
autoplay: autoplay,//是否自动播放（选填）
animationData:animationData,
rendererSettings:{
context:context,
},
assetsPath:assetsPath,
})
animation.setSpeed(animationSpeed)
},
changeAnimation(animationType,animationSpeed){
console.info('_that.data.animationType',_that.data.animationType)
_that.setData({
animationType:animationType
})
let animationData = null,assetsPath = '',loop = true,autoplay = true
if(animationType == 0){
//跑步
animationData = require("../../animation/running/running.js")
}else if(animationType == 5){
//走路
animationData = require("../../animation/walking/walking.js")
}
if(animation && animation.animationID){
_that.changeAnimationType(animationData,assetsPath,animationSpeed,loop,autoplay)
}else{
_that.draw(animationData,assetsPath,animationSpeed,loop,autoplay)

}

},
`
当调用loadAnimation超过2次的时候，整个页面就会卡死，在安卓手机下甚至会崩溃

@bigkrys 请问小程序奔溃的问题有解决方案么？

每次重新setup一下
